SPECIFICATION forming part of Letters Patent No. 756,250, dated April-5, 1904. Y

Application filed September r20, 1901. Serial No. 75,92%. (No model.) i

To LZZ whom it 10aa/y concern:

Be it known that I, LESTER F. LERGHNER, dental surgeon, residing at Charlottenburg,

Germany, have invented Improvements in.

Washbowls or Spittoons, of which the following is a specification.

The object ofthe present invention is to provide an improved washbowl or spittoon for dental or other purposes which shall meet all sanitary requirements.

rlhe invention consists of the parts and combinations of parts, as will be hereinafter fully described, and pointed out in the appended claims. n

'In the drawings accompanying this specification and forming part thereof, Figure 1 is a vertical section. Fig. 2 is a vertical rsection of a modication; Fig. 3, a top plan view of Fig. l; Fig. 4, an enlarged sectional view of a portion of the basin, showing the mounting of the air-compressing bulb; Fig. 5, a detail section showing the filling-inlet, and Fig. 6 a side and a top view of a trap 'for teeth and cotton.

Referring more particularly to the drawings,

the washbowl or spittoon is divided into two water-chambers A and B by a partition 0;, and the upper chamber A has a top o, inclined downwardlytoward the center, forming a receptacle for receiving the expectorations. In

the-center of the top c is a'waste-pipe d, whichV may be closed by a stopper e and which de-l lower part of c, vn'earthe waste-pipe CZ, smallV holes Z2, are arranged, which, with the openings g, serve as passages for the water from the chambers to the basin. YThe upper chamber A is provided with a passage z', through which a pipe'j depends into the lower chamber B, and to this pipe j an air-compressing bulb is fastened. The top c of the chamber A near its edge is provided with an opening Z, through which said chamber may be filled, and a valve m is provided to close said opening.

. The washbasin or spittoon, as well as receptacle for waste water, may be supported in any convenient manner or, as in the present case, by a three-legged standard n.

In operation after the air-compressing bulb 7c, together with the pipe y', is removed the lower chamber B is lled with water, and then the bulb Z0 and `pipe j are placed within the passage c'. The upper chamber Ais then filled by opening the valve m after closing the holes t by any convenient means, and after filling this chamber the valve m is closed. lf it is desired to lill or clean the washbasin or spittoon by the openings g, the bulbk is pressed,

and consequently the air in the lower chamberB compressed, and water is forced through the pipes 0 and out of said openings, or if it is desired to fill or clean the basin from below it is accomplished by the holes ZL, the valve m being opened, so that the water by its natural pressure-#Z1 e., by the influence of the airpre'ssure from outside-forces its way through the holes in the lower part of the basin and fills or cleans the same. It is also obvious that by pressing the ball Zn and opening the valve m at the same Vtime the basin will be lled or cleaned from above and below at the same time.

The air-pressing bulb is provided with an aperture p,- through which the same iills itself with air in the ordinary way after being pressed, and therefore doesnot suck up water, and said aperture is closed by the hand or linger when the bulb is pressed to drive the water through the holes gin the manner already described. Below the bulb 7c the pipe j may be provided with a cockq, so that water may be drawn from the chamber B directly, which is done by pressing the bulb, so that it sucks up water which is discharged through said cock.

Fig. 2 shows a Inodication bywhich the described process can beV accomplished more automatically. A and B again represent the upper and lower water-chambers; g, the openings in the top c `of the chamber A. The chamber A is filled through the opening Z', as in Fig. l, the valve m only being seen in this `figure in a raised position, while the chamber B is lled through a tube Z, closed by a valve m. 0 represents the pipes connected to IOO said Openings g,- but in this instance they do not lead to the lower chamber, but only to the bottom of the upper' chamber A. d is the waste-pipe connecting the basin with the receptacle f, receiving the waste water. Below the receptacle f a chamber s for compressed air is arranged, in which the air can be compressed in the ordinary wayvfor instance, by attaching an air-'pump to the opening t. From the air-compressing chamber s a pipe or hose ful leads to a jet o on the upper chamber A, and when the jet is opened the compressed air enters the chamber A and forces the water through the pipes 0 and holes g in the manner and for the purpose already described. In this construction the upper chamber Aserves to'iill or clean the basin, while the water in the lower chamber is kept for other purposes, and by opening the cock w this water can be withdrawn, and a glassz in a hanger y may be filled independently of the water-chamber A. The passage Z in this form serves to fill the lower chamber B. A removable bottom c', having the form of the basin, is fitted within the same and extends upwardly to a point just below the openings, so that the water in issuing from saidopenings strikes its sides. This bottom may be removed and cleaned, so that the washbasin or spittoon will always look neat. Y.

Fig. 6 represents a trappfor pulled teeth and cotton, which is placed in the waste-pipes and which is made of wire-netting, having two arms extending outwardly therefrom, by means of which the trap is held in position in the pipe, as seen in Fig. 2.

It may be mentioned that the holes g may be so arranged as to let the water out sidewise, as seen in Fig. 1, so that the sides of the basin are struck by full force of the Water, assuring a thorough cleaning. The removable receptacle f of Fig. l may be emptied by opening a cock secured thereto.

Having thus described the invention, the following is what is claimed as new therein:

l. In a device of the class described, the combination of a washbasin, provided with a central drain-opening, and a series of holes in the lower part of said basin surrounding the central drain-opening, an air-tight chamber surrounding the basin, provided with a fillingopening; and a valve adapted to close the filling-opening, holding the water within the chamber when closed and allowing the Water in the chamber to pass out of said chamber into the basin, through the series of holes, when opened.

2. In a device of the class described, the

combination with awater-chambcr, of a washbasin provided wlth a central opening, a series of holes in the lower part of the basin, surrounding the opening, a series of openings.

near the upper edge of the basin; and independent pipes depending into the water-chamber for delivering water through the series of openings.

3. In a device of the class described, the combination of a Washbasin, two chambers disposed beneath the same; said washbasin having communication with one of the chambers to deliver iuid to the upper part thereof, and communication with the other chamber to deliver fluid to the lower part thereof.

4. In a device of the class described, the combination of the washbasin provided with a series of openings in the upper part thereof and a series of openings in the lower part, two water-chambers disposed beneath said basin, one of said chambers communicating with the basin through the holes in the lower part, a series lof tubes forming the communication between the other chamber and the basin, a drain-tube depending from the basin through the chambers, and means for forcing Water from both chambers to the basin.

5. In a dental spittoon, the combination with a portable stand, of a receiving-basin at the top of the stand provided with a central outlet, aremovable trap mounted in said outlet, a waste-receptacle carried by the stand and located beneath said outlet, a Water-chamber on said stand surrounding the receivingbasin and above the waste-receptacle, said receptacle being provided with a plurality of water-supply openings arranged around its upper portion and a bulb for forcing the water from the water-chamber through the openings surrounding the upper portion of the receiving-basin.

6. In a dental spittoon the combination with the portable stand, a receiving-basin supported on the stand and provided with an outlet, a waste-receptacle carried by the stand and located beneath the outlet, a water-chamber carried by the stand and surrounding the basin, and located above the receiving-receptacle and an air-pressure device for forcing the water from the water-chamber into the basin.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
